Harry Potter star Emma Watson was spotted out and about on a hike in Saint Tropez in a little black dress. The British actress explored the coastal town on the French Riviera in her interesting activewear attire, layering the racy long-sleeved cover-up over her bold red bikini while wearing a pair bright turquoise sneakers. Watson also piled on the accessories, wearing two beaded charm necklaces, gold earrings, several rings and black sunglasses.
